Definitions

  • the present invention relates to the field of agricultural and industrial works small equipment.More specifically,the inventon relates to an enlarged load tiller easy to manipulate destined for little areas,where the tractors can't be used,like in a closed space or on a narrow surface.
  • a tiller according by the present invention obtains a better adaptation at various work exigencies, using one of the two moving systems, which it is providing. So, if for on public roads run, it will use a known wheeled system with pneumatic tires (3), obtaining a rapid speed range in transport; for land works it will use a chain track (5) system, obtaining an enlarged load concomitantly with a speed diminution.
  • the moving system substitute is an elementary operation, which don't requires the useless system dismantling.
  • a simple downward chain track assemblies rotation succeeded by a bar (6) fitting is enough for to pass from the wheeled system to the chain track system. This operation is reversible.
  • FIG. 1 A tiller with the chain track moving system in act prepared for work, and the rear three-point-linkage mechanism fitted.
  • FIG. 1 A tiller with the chain track moving system in act prepared for work and the front three-point-linkage mechanism fitted.
  • FIG. 1 A tiller with the wheeled system in act, prepared for work.
  • a tiller using two moving alternate systems are composed of an engine- gearbox unit l,as they are using for the known tillers.
  • Each gearbox output shaft act a chain track wheel 2 and a pneumatic tire wheel 3.
  • the chain track wheel 2 is leaning on two bearings included in a frame 4.
  • a chain track 5 is running around this frame.
  • the frame 4 includes and a chain track leaning mechanism and a chain track tensile mechanism.
  • the external chain track radius on the wheel 2 is less than the tired wheel 3 dynamic radius. For the same output shaft torque, the peripherial load will be more for the chain track than the tired wheel.
  • a few adjustable bars 6 keep the assembly rigidity and are upholding a three-point-linkage mechanism 7,and a small hydraulic cylinder 8.
  • a hydraulic pump 9 is acting by the tiller handle and is using to control the three-point-linkage mechanism attitude.
  • old tiller couplings 10 are recommended.
  • One or more weights 11 can use to balance of the tiller.
  • the figure 1 shows a tiller according the present invention with booth chain tracks 5 sitting on the soil. Concomitantly, booth tired wheels 3 are without the soil contact. In this three-point-linkage mechanism rear position, the tiller can perform many agricultural works like to plough and to weeds control.
  • the figure 2 is differing by the figure 1 because the same three-point- linkage mechanism position (7) has a front fitting positin.
  • This tiller variant can perform many works for earth digging, for various materials loading and transport, snow removing, pest control and others services.
  • FIG 3 shows a tiller according by the present invention with booth chain tracks assemblies in an upward position rotate and fix.
  • Booth pneumatic tired wheels are on the soil contact. This position permits the movement on public roads and all the other works possible in the old wheeled variant.
  • a tiller comprising two moving systems which are working alternate .
  • the first moving system is wheeled (3); the second use two chain tracks (5) assemblies and the work system change is basing on an elementary rotation of chain tracks assemblies following a fix.
  • a tiller of claim 1 where on the chain tracks assemblies has a three-point-linkage rear mechanism (7).
  • a tiller of claim 2 where on the chain tracks assemblies has a three-point-linkage front mechanism (7).

Abstract

L'invention concerne un cultivateur n'étant pas conduit par une personne, utilisant deux systèmes alternés de mouvement équipé d'une boîte de vitesse (1), de deux roues (3), de deux chenilles (5) assemblées et d'un mécanisme (7) à trois points de connexion commandé par un système hydraulique comprenant deux cylindres hydrauliques (8) et une pompe (9). Le cultivateur est caractérisé par deux systèmes mobiles, qui fonctionnent en alternance; par un système à roues et un système de chenille; et par un système hydraulique à trois points de connexion qui peuvent être utilisés dans la position de marche arrière ou dans la position de marche avant.
